Type material.

Holotype: China • male ( ZAFU); Yunnan Province, Pu’er City , Jinggu County; 1 Jun. 2025; Quan-Fu Duan leg; ZAFU -IC-200001 . Paratypes: China • 1 female & 2 nymphs ( ZAFU); Luo-Jiang Liu leg; same collection data as holotype; ZAFU -IC-200002 to 200004 • 1 female & 2 nymphs ( SWU); Luo-Jiang Liu leg; same collection data as holotype; SWU -B-CC-010074 to 010076 .

Diagnosis.

The male tegmina maculae of this species most closely resemble those of P. wooi ( Qiu, Che & Wang, 2018) . However, in natural posture, the medial black maculae on both tegmina are fused in this species, and the abdomen (excluding the terminal segment) is light yellowish brown. In contrast, P. wooi exhibits non-fused medial black maculae on the tegmina in natural posture, with the abdomen (excluding the terminal segment) being dark yellowish brown. Furthermore, females of this species possess four symmetrical yellow maculae near the anterior margin on both the mesonotum and metanotum, whereas P. wooi females bear only two conspicuous symmetrical yellow maculae solely on the metanotum.

Description.

Holotype. Measurements (mm). Overall length (including tegmen): 26.27; body length: 17.82; body width (tegmina not included): 8.46; tegmen length × width: 21.73 × 7.74; pronotum length × width: 7.42 × 4.85.

Coloration. Pronotum black, anterior margin white. Tegmina and hind wings yellowish brown, maculae black (Fig. 2 A, E View Figure 2 ). Eyes, vertex, post-clypeus and spaces between ocelli black. Ocelli and antennal sockets white. Ante-clypeus yellowish white. Antennae and labrum yellowish brown. Labial palpi brown (Fig. 2 G View Figure 2 ). Legs black brown, spines yellowish brown to black. Pulvilli and arolia white. Sterna yellowish brown, margins and distal part black (Fig. 2 B View Figure 2 ).

Body. Head: Sub-rounded, nearly completely hidden under pronotum. Eyes and ocelli well-developed. Interocular space narrower than the distance between ocelli, the latter narrower than the distance between antennal sockets (Fig. 2 G View Figure 2 ). Pronotum: Oval-shaped, widest near the middle. Surface densely covered with short setae and long pubescence, central portion bearing symmetrical black stripes. Anterior whitish margin narrow, clearly delineated from black areas (Fig. 2 E View Figure 2 ). Tegmina and hind wings: Densely covered with black maculae, markings on the basal lateral margins and mid-region more densely distributed than other areas (Fig. 2 A View Figure 2 ). Legs: Slender, front femur Type C 1. Pulvilli and arolia present (Fig. 2 B View Figure 2 ). Abdomen: Smooth. Supra-anal plate transverse, pubescent, posterior margin protruded medially. Paraprocts simple (Fig. 2 I View Figure 2 ). Subgenital plate with short setae, hind margin slightly asymmetric. Styli thin and long (Fig. 2 J View Figure 2 ). Genitalia: Well-sclerotized. L 1 apically bearing two short branches; the two basal branches distinct and elongated. L 2 arcuately curved. Genital hook (L 3) medially swollen, tapering toward hooked apex. L 4 M broadly lamellate. L 4 N well-developed; pda and paa strongly curved. L 8 irregular, narrow and plate-like. R 1 M stoutly expanded terminally. R 1 L elongate and banded. R 2 divided into two chunks. R 3 broadly concave (Fig. 2 K, L View Figure 2 ).

Female paratype (mm). Body length: 20.54; body width: 12.02; pronotum length × width: 8.91 × 5.58.

Coloration. Terga reddish brown to blackish brown, with four symmetrical yellow maculae at the anterior margin of the meso- and metanotum (Fig. 2 C View Figure 2 ). Pronotum dark reddish brown, pubescence light reddish brown (Fig. 2 F View Figure 2 ). Vertex, eyes, space between ocelli and post-clypeus black. Antennal sockets white. Antennae yellowish brown. Ocelli, ante-clypeus, and basal part of labrum pale yellow. Middle and distal part of labrum yellowish brown. Legs dark brown, spines reddish brown to black. Sterna brown to yellowish brown. Subgenital plate black (Fig. 2 D, H View Figure 2 ).

Body. The widest point of pronotum near the hind margin. Anterior whitish margin absent, bearing symmetrical black stripe medially (Fig. 2 F View Figure 2 ). Ocelli degraded to two spots. Interocular space almost equal to the distance between antennal sockets, both wider than the distance between ocelli. Front femur Type C 1. Arolia and pulvilli absent (Fig. 2 D, H View Figure 2 ).

Nymph. Pronotum also with four symmetrical yellow maculae, the rest similar to the female.

Ootheca. Unknown.

Etymology.

This species is named after the collector, Mr Quan-Fu Duan, in recognition of his contribution to its discovery.

Remarks.

This species exhibits the smallest genetic distance (8.75 %) to P. vestis , while distances to all other congeners exceed 9 %. The male forewing maculae and the four distinct maculae on the female mesonotum and metanotum readily distinguish this species from other members of the genus, providing robust morphological support for its establishment as a new species.
